cables 8 or 9 tend to swing out of their normal path, due to vibrationsor sudden stoppings of the car, said resilient mounting tending tofollow the movement of the cable, it stops the cable vibrations throughthe absence of'a solid connection vbetween the end ofthe cable, and thecar frame-work.

To recapitulate the flexible mounting of the end of the cab e eliminatesto 'a-large extent the swaying ofsaid cable. The combination of a singlemounting .plate, such as devices, whereby the car operating cables andthe counter-weight cables are flexibly attached to the car, serves toprevent sudden jars to the car, and at the same .ime serves to preventbreakage of the cable at v the socket 17 which is also likely to becaused by the swaying of the cables.
